My wife teaches at the local Vocational school, mostly EMS and public safety kids. Most are ok, a few are terrible. As always, sadly, the few try to dictate how things go during class, there are patterns as to who acts up but public decorum here prevents my saying who. To make a long story short, she is done, finished and won't be going back as the pay is not worth the hassle and BS and liability. It's really bad folks, we are in trouble.
All of us were teens at one time. I remember bringing home my first Black Sabbath album. I will agree though that this batch seems to be a bit different. It should be no surprise to us at all.
Be yourself. Don't compromise. Be fair and equal. Good luck.
